  • the present invention is not limited to this, and the inspection device 14 may be provided on a conveyance drum other than the conveyance drum 10B constituting the conveyance drum row 10 as long as it is on the downstream side of the catcher drum.
  • the inspection apparatus 14 shown in FIG. 4 may be provided in a section other than the transport section 8 of the manufacturing machine 1 or in a manufacturing machine for smoking articles other than the manufacturing machine 1, or a rod-shaped smoking rod separate from the manufacturing machine 1 You may provide independently as an inspection apparatus 14 of this.
  • the inspection device 14 is provided in the transfer drum row 10 of the manufacturing machine 1, or separately provided as the inspection device 14 separate from the manufacturing machine 1.
  • the present invention is widely applicable to the inspection of rod-like articles for smoking by the inspection method described below, which is not limited to the presence or absence of the use of.
  • FIG. 12 is a flowchart showing the procedure of the inspection method.
  • a plurality of lights having different wavelength distributions, that is, different colors are generated (light generation step).
  • the inspection light Li is formed from a plurality of lights (adjustment step).
  • a color tone process is performed in which the color of the inspection light Li is adjusted by mixing the lights generated in the light generation process.
  • the inspection light Li is irradiated to the rod-like article (irradiation step).
  • the irradiated inspection light Li receives the measurement light Lm obtained by acting on the rod-like article (light receiving step).
  • the quality of the rod-like article is determined based on the measurement light Lm (determination step), and the inspection procedure is ended.
  • the rod-shaped articles determined to be defective in the main inspection are appropriately excluded.
  • the color of the inspection light Li is adjusted by adjusting the intensity of each light generated in the light generation process.
  • the inspection light Li is adjusted to the color that can distinguish the boundary B of each segment, so that the disposition of each segment can be easily made good. It can be determined.
  • the influence of the capsule C on the measurement light Lm can be reduced by adjusting the inspection light Li to the same color as the object. Since the boundary B of each segment can be clearly identified and the type of each segment can also be identified, the inspection accuracy of the rod-like article can be further enhanced.
